3 Fault Tolerance Concepts With Examples

3.1 Introduction

A major purpose of this document is to define system fault tolerance concepts in an understandable manner. To help the reader understand the concepts, each concept is illustrated by a set of examples after it is defined. Where possible the same two examples are used throughout the document.

It is often easier to understand a concept using an analogy. This avoids the problems associated with the unintentional overloading of the meaning of words that often occurs in a familiar context. Thus one of the two examples that will appear throughout this document is a (simplified) highway bridge over a river. The other example will be in the probably more familiar world of computers.
